LIQUID-FUEL BURNER.

eveaeo.

To all whom it may concern:

I 3e it known that I, JOHN I. Ronnnrs, a cltizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Liquid-Fuel Burner, of whichthe following is a specification.

This invention relates to that class of liquid fuel burners which aredesigned to be supported in the lid opening of an ordinary coal burningstove, and in which vapor or gas 13 generated in a closed chamber fromwhich it is fed to a burner.

It is the object of the present invention to provide in a burner of thistype an improved flame deflector for directing the flame to thegenerator, and thus providing for a more rapid vaporization of theliquid fuel.

Another object is to provide improved supporting means which enables theburner to be readily applied to any ordinary coal burning stove.

The invention also has for its object to provide a burner embodyingcertain novel structural details as will be hereinafter described andclaimed.

In the accompanying drawings: Figure 1 is a side elevation of the burnerin position on a stove. Fig. 2 is a top plan view, Fig. 8 is a bottomplan view and Fig. 4 is an end view of the burner. Fig. 5 is atransverse section on the line 5-5 of Fig. 2. Fig. 6 is a transversesection on the line 6-6 of Fig. 1.

In the drawings, 10 denotes the top of the stove, and 11 one of theusual lid openings.

. Over this opening is placed a plate 12 which supports the entireburner structure, said plate taking the place of the lid. The bottom ofthe plate carries a bar 13 which extends across the lid opening intoengagement with the under side of the stove top, the bar being connectedto the plate by bolts 14. Upon tightening up these bolts, the plate issecurely held in place over the lid opening.

The generator or vaporizing chamber is located within the fire pot ofthe stove, beneath the plate 12, and comprises a casting 15 havingformed therein a looped passage 16, one end of which is connected to aninlet pipe 17, and the other end to an outlet pipe 18 leading to theburner.

The burner comprises an elbow 19 screwed at one end on the pipe 18 downagainst the top of the plate 12, said pipe extending through an openingin the plate. The

pends from the plate, through the lid opena ing, into the fire pot ofthe stove, and is connected to the generator already doscribcd, thelatter having a nipple on top to which the pipe connects. The pipe isinclosed by a sleeve located between the top of the nipple and the underside of the plate 12. The inlet pipe 1'? also extends to the generatorthrough an opening made in the plate 12, and through the lid opening,and on its upper edge is screwed into an elbow 23, said elbow screwingdown against the top of the plate. The lower end of the pipe 17 screwsinto a nipple on the generator. This pipe is also surrounded by a sleevein the same manner as the pipe 18.

By the structure herein described, the inlet and outlet pipes are alsomade to serve as a support for the generator. The elbow 23 is connectedto a short section of piping 24 leading to the casing 25 of a valvewhich controls the flow of fuel to the generator. From the valve casing,another pipe 25 leads to the tank or other source of supply (not shown).At the bend of the passage 16, the generator has a threaded aperturewhich is closed by a screw plug 27 which, upon being removed, permitsaccess to the passage for the purpose of cleaning the same.

In the top of the generator is a depression 28 forming a cup to holdsupply of fuel when starting the burner. The opening 21 is surmounted bya hood 29 into the open end of which the tip 20 discharges, the top wallof the hood being presented at an oblique angle to the plate 12. On thebottom of the plate is a deflector comprising a flange 30 formedintegral with the plate, and located above the generator. One side ofthe flange is curved, and forms a continuation of the inner side of thetop wall of the hood. The tip 20 is presented at the same angle as thetop wall of the hood.

To start the burner, a small supply of oil is allowed to run into thedepression 28. This oil being ignited, the oil in the generator isheated, and the vapor thus generated issues from the tip, and passesinto the hood 29 and through the opening 21. The vapor is mixed with airpassing through the hood, and is burned in the fire pot of the stove.Air to support combustion is also supplied through the stove. The airsupply is regulated by the dampers of the stove. The hood 29 and thedeflector 3O spread the flame, and direct it to the generator, wherebythe latter is kept intensely heated and a thorough and rapidvaporization of the oil is efi'ected. On top of the plate 12 are lugs 31Which are provided to support cooking utensils in order that the spaceon the stove occupied by the plate may not be Wasted.

Nhat is claimed is:

1. In a liquid fuel burner, a plate having an opening, a hoodsurmounting said opening, and having a top Wall extending at an obliqueangle to the plate, a burner tip presented into the open end of'thehood, a generator beneath the plate, a supply connection to thegenerator, an outlet from the generator to the burner, and a deflectoron the bottom of the plate forming a contii'iuation of the aforesaidWall of the hood, said deflector being presented in the direction of thegenerator. 7

2. In a liquid fuel burner, a plate having an opening, a hoodsurmounting said opening, and having a top Wall extending at an obliqueangle to the plate, a burner, tip pres sented into the open end of thehood, a generator beneath the plate, a supply connection to thegenerator, an outlet from the generator to the burner, and a deflector"on the bottom of the plate, said deflector having a curved surfaceforming a continuation of the inner surface of the top Wall of the hood,

and said curved surface being presented in j the direction of thegenerator.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signa- V t-ure in the presence of two Witnesses.
